From your experts in precision couplings

The concept of fatigue resistance in metallic coupling design, with the goal of infinite service life, is one which has been valued by R+W for many decades.  With the introduction of its SURVIVOR series disc pack couplings, R+W has taken another step forward in delivering efficiency through coupling design to users of industrial drives.  The SURVIVOR series, like all R+W couplings provides a significant technical advantage.  The disc pack assemblies are mounted into the couplings by means of pure friction.  This purely backlash free friction fit serves to eliminate problems associated with stress concentration, backlash, and micro-movements, all of which can result from transmitting torque across the shanks of shoulder bolts. The frictional connection of the disc packs further increases service life, in addition to making the complete coupling assembly more torsionally stiff.
